Abstract

The invention relates to a gasoline and a method for producing the gasoline, whose specific name is a high-grade environment-friendly lead-free gasoline. According to mass percentage, the compositions of the gasoline comprise light hydrocarbon oil 35-45%, carbinol 45-55%, stable improving agent 8-10% and core additive 0.8-1.2%. The gasoline has the advantages that first, carbon and oxygen fully contact, combustion is led to be more thoroughly and more sufficient, thereby improving firepower, increasing heating value, and leading power to be stronger, second, the gasoline thoroughly clears carbon deposition in a motor, which avoids coking, third, the gasoline lowers smoke exhausting quantity, which is better accordant to environmental protection requirements, fourth, the performance of carbinol is stabilized and improved through increasing stable improving agent, which increases component occupation amount of carbinol in gasoline, and the phenomenon of layering can not be produced, and production cost and corrosivity of gasoline are lowered, fifth, when in use, the gasoline has no gas blockage, which can be mixed at random to use with other gasoline, and has more practicability.

Description

A kind of high-grade environment protection lead-free gasoline and preparation method thereof

Technical field

The method that the present invention relates to a kind of high-grade environment protection lead-free gasoline and make this gasoline.

Background technology

The shortcoming and the difficult point of methanol gasoline technology existence at present can go out when methyl alcohol surpasses 15% exactly

Now do not dissolve each other and demixing phenomenon, easy vapour lock, ignition time do not match, are short of power during use, easily to engine generation corrosion and to shortcomings such as rubber item swellings.Owing to have these problems, be difficult on market, sell and use.

Summary of the invention

The wherein technical problem that the present invention will solve provides a kind of high-grade environment protection lead-free gasoline.

According to above-mentioned technical requirements, the present invention realizes by the following technical solutions:

A kind of high-grade environment protection lead-free gasoline, according to mass percent, this gasoline component is:

Light hydrocarbon oil: 35～45%, methyl alcohol: 45～55%, stablize activator: 8～10%, core additive 0.8～1.2%,

Wherein, stablizing the activator component is: C12---C14 fat alcohol mixture 3～4%, ethanol 2～2.5%, acetone 2～2.5%, dimethylbenzene 1～1.2%, secondary octanol 1～1.2%.

Wherein, the core additive is composed of the following components by weight percentage: acetone 20%～25%, isopropylcarbinol 10%～21%, kerosene 5%～15%, dimethylbenzene 25%～40%, gasoline detergent, antioxygen, antiknock, anti-rotten standard-increasing agent 6%～14%.

Perhaps, the core additive by weight percentage also can be composed of the following components: Virahol or isopropylcarbinol 20%～50%, dicyclopentadienyl iron 5%～20%, dimethyl carbonate 6%～35%, Organic Manganese 5%～20%, the naphthenate of calcium, barium, nickel, chromium, copper or in the sulfonate any 1%～10%.

Another technical problem that the present invention will solve provides a kind of manufacture method of above-mentioned high-grade environment protection lead-free gasoline, and the step of described method is:

The first step is prepared each component by above-mentioned requirements;

In second step, fatty alcohol mixture, ethanol, acetone, toluene and secondary octanol mixing furnishing are stablized activator; With acetone, isopropylcarbinol, kerosene, dimethylbenzene and gasoline detergent, antioxygen, antiknock, anti-rotten standard-increasing agent mixing furnishing core additive, perhaps Virahol or isopropylcarbinol, dicyclopentadienyl iron, dimethyl carbonate, Organic Manganese and calcium, barium, nickel, chromium, the naphthenate of copper or any mixing furnishing in the sulfonate are stablized activator.

In the 3rd step, will stablize activator and join in the methyl alcohol;

In the 4th step, the core additive is joined in the 3rd step gained mixed solution;

The 5th step added light hydrocarbon oil in the 4th step gained mixed solution and stirred 20～30 minutes, and standing and reacting is 4～8 hours again, filters the oil that gets product then.

Advantage of the present invention is:

1. carbon fully contacts with oxygen, makes burning more thorough, more abundant, thereby improves firepower, increases calorific value, makes power more powerful;

2. thoroughly remove in-engine carbon deposit, prevent coking;

3. reduction exhaust smoke level, more compliance with environmental protection requirements;

4. stablize activator by increasing, stablize and improved the performance of methyl alcohol, can make methyl alcohol composition occupancy volume in gasoline increase and can not produce demixing phenomenon, reduced the corrodibility of production cost and gasoline;

5. do not have vapour lock when using, can mix use arbitrarily, have more practicality with other gasoline.
